Beet

The Minecraft pack development kit.

Introduction

Minecraft resource packs and data packs work well as distribution formats but can be pretty limiting as authoring formats. You can quickly end up having to manage hundreds of files, some of which might be buried within the bundled output of various generators.

The beet project is a development kit that tries to unify data pack and resource pack tooling into a single pipeline. The community is always coming up with pre-processors, frameworks, and generators of all kinds to make the developer experience more ergonomic. With beet you can seamlessly integrate all these tools in your project.

Library

from beet import ResourcePack, Texture

# Open a zipped resource pack and add a custom stone texture
with ResourcePack(path="stone.zip") as assets:
    assets["minecraft:block/stone"] = Texture(source_path="custom.png")

The beet library provides carefully crafted primitives for working with Minecraft resource packs and data packs.

• Create, read, edit and merge resource packs and data packs
• Handle zipped and unzipped packs
• Fast and lazy by default, files are transparently loaded when needed
• Statically typed API enabling rich intellisense and autocompletion
• First-class pytest integration with detailed assertion explanations

Toolchain

from beet import Context, Function

def greet(ctx: Context):
    """Plugin that adds a function for greeting the player."""
    ctx.data["greet:hello"] = Function(["say hello"], tags=["minecraft:load"])

The beet toolchain is designed to support a wide range of use-cases. The most basic pipeline will let you create configurable resource packs and data packs, but plugins make it easy to implement arbitrarily advanced workflows and tools like linters, asset generators and function pre-processors.

• Compose plugins that can inspect and edit the generated resource pack and data pack
• Configure powerful build systems for development and creating releases
• First-class template integration approachable without prior Python knowledge
• Link the generated resource pack and data pack to Minecraft
• Automatically rebuild the project on file changes with watch mode
• Batteries-included package that comes with a few handy plugins out of the box
• Rich ecosystem, extensible CLI, and powerful generator and worker API

Installation

The package can be installed with pip.

$ pip install beet

To create and edit images programmatically you should install beet with the image extra or install Pillow separately.

$ pip install beet[image]
$ pip install beet Pillow

You can make sure that beet was successfully installed by trying to use the toolchain from the command-line.

$ beet --help

Contributing

Contributions are welcome. Make sure to first open an issue discussing the problem or the new feature before creating a pull request. The project uses poetry.

$ poetry install --extras image

You can run the tests with poetry run pytest. We use pytest-minecraft to run tests against actual Minecraft releases.

$ poetry run pytest
$ poetry run pytest --minecraft-latest

We also use pytest-insta for snapshot testing. Data pack and resource pack snapshots make it easy to monitor and review changes.

$ poetry run pytest --insta review

The project must type-check with pyright. If you're using VSCode the pylance extension should report diagnostics automatically. You can also install the type-checker locally with npm install and run it from the command-line.

$ npm run watch
$ npm run check

The code follows the black code style. Import statements are sorted with isort.

$ poetry run isort beet tests
$ poetry run black beet tests
$ poetry run black --check beet tests
